A base assembly for a sunshade includes a base having a recessed portion defined in an upper side thereof, allowing additional weight to be removably inserted into the recessed portion. The base further includes a tubular portion for receiving a lower end of a post of a sunshade. A spacer is preferably attached to an underside of the base for keeping the base at a level above ground. The tubular portion of the base may include a threaded section. A sleeve has a threaded section for threadedly engaging the threaded section of the tubular portion of the base, with the lower end of the post being received in the lower end of the sleeve.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a base assembly for a sunshade. In particular, the present invention relates to a base assembly that can be used with sunshade posts of various diameters.

2. Description of the Related Art

FIG. 1 of the drawings illustrates a sunshade 1 with a conventional base 12. FIG. 2 is an enlarged sectional view of the base 12 in FIG. 1. The base 12 is attached to a lower end of a post 11 of the sunshade 1 for supporting the sunshade 1 in an upright position. The base 12 includes a main portion 121 that is a disc-like member made of cast iron and a sleeve 122 fixed on top of the main portion 121. The lower portion of the post 11 is placed into the sleeve 122, and two screws 124 are extended through screw holes (not labeled) of the sleeve 122 to be in frictional contact with an outer periphery of the lower portion of the post 11. The sunshade 1 is thus kept in an upright position.

Spacers (not shown) are often attached to an underside of the main portion 121 for preventing the main portion 121 from rusting. However, the padding members are apt to be disengaged from the main portion 121 and thus lost. Further, when the canopy of the sunshade 1 is in an opened state, the sunshade 1 is apt to fall down when subject to strong winds. To avoid falling down of the sunshade 1, the weight of the base 12 must be increased, which increases the burden of moving the base 12. Attachment of an additional weight to the underside of the base 12 has been proposed, yet this involves placing the bulky base 12 down to a horizontal position before attachment of the additional weight and moving the base 12 (which is now heavier) back to the upright position, which is troublesome and laborious.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 3 through 5, a base assembly in accordance with the present invention is designated by “2” and attached to a lower end of a post 11 of a sunshade 1. The base assembly 2 includes a base 21, a sleeve 22, and at least one weight 25. The base 21 is made of cast iron to provide a stable support for the post 11 of the sunshade 1 and includes a recessed portion 212 in an upper side thereof. The recessed portion 212 is preferably annular and concentric with the base 21. A tubular member 211 is provided on a central portion of the upper side of the base 21. The weight 25 is removably placed into the recessed portion 212. In this embodiment, the weight 25 is a disc-like member having a central hole 251 through which the tubular member 211 extends; namely, the weight 25 is mounted around the tubular member 211. Preferably, the weight 25 includes a non-circular recess 252 in an underside thereof, and a non-circular extension 215 is formed on an outer periphery of the tubular member 211 or a bottom wall 213 delimiting the recessed portion 212, thereby securely positioning the weight 25. Preferably, a peripheral wall 214 delimiting the recessed portion 212 includes two notches 216 to allow easy removal of the weight 25.

The sleeve 22 has a lower end having an outer threading 222 for threadedly engaging with an inner threading 219 of the tubular member 211, and the lower end of the post 11 of the sunshade 1 is inserted into the sleeve 22. Preferably, the sleeve 22 has an inner diameter the same as an outer diameter of the lower end of the post 11 of the sunshade 1, best shown in FIG. 5. A cover 24 is mounted on top of the base 21 and has a screw hole 241 threadedly engaged with the outer threading 222 of the sleeve 22. The user may remove the cover 24 and then place the weight 25 into the recessed portion 212 before attachment of the post 11. The weight 25 may be a block with or without hole, with the tubular member 211 extending or not extending through the hole of the block. Of course, the user may add as many weights as possible into the recessed portion 212 of the base 21 to provide a stable support for the post 11.

A spacer 23 is mounted to an underside of the base 21 to keep the base 21 at a level above the ground, thereby preventing the base 21 from rusting. The spacer 23 is made of plastic or rust-resisting material. In this embodiment, the spacer 23 is a ring, and a plurality of screws 26 are extended through holes 218 in the base 21 into screw holes 233 of the spacer 23. Further, a plurality of protrusions 232 are formed on an underside of the spacer 23 to keep the base 21 at a level above the ground, best shown in FIG. 5.

FIG. 6 illustrates a modified embodiment of the invention, wherein the sleeve 22 in FIG. 6 has a diameter smaller than that of FIG. 5 for receiving a post 11 having a smaller diameter. An adaptor sleeve 27 is mounted between the tubular member 211 of the base 21 and the sleeve 22. The adaptor sleeve 27 has an outer threading 271 for threadedly engaging with the inner threading 219 of the tubular member 211 and an inner threading 272 for threadedly engaging with the outer threading 222 of the sleeve 22. Thus, the base assembly 2 in accordance with the present invention can be used with sunshade posts of various sizes.

FIGS. 7 and 8 illustrate a modified embodiment of the invention, wherein the sleeve 22 has no outer threading and the tubular member 211 has no inner threading. Further, the sleeve 22 and the tubular member 211 are integrally formed as a single tubular member or sleeve 22 for receiving a lower end of a post 11 of a sunshade 1. A screw or bolt 28 is extended through a screw hole 225 of the sleeve 22 to be in frictional contact with an outer periphery of the lower end of the post 11, thereby keeping the post 11 in an upright position.
